AnswersDriveNormally I have always taken the Natural Numbers to start at 1 and not to include zero. Natural Numbers are 1,2,3,4,5, [] and Whole numbers are 0,1,2,3, According to Wikipedia: In mathematics, a natural number is either a positive integer (1, 2, 3, 4, ) or a non-negative integer (0, 1, 2, 3, 4, ).
Also know, why is zero not a counting number?
Zero is known as the neutral integer, or the whole number that comes in the middle of the positive and negative numbers on a number line. Zero does not have a positive or negative value. Zero is however considered a whole number, which in turn makes it an integer, but not necessarily a natural number.
1
What is the difference between a natural number and a whole number?
Natural Numbers are also called counting numbers. Zero is the only whole number which is not a natural number. It is represented by 0. "Zero is the only difference between natural and whole numbers."
2
What is the highest whole number?
So, 0, 1, 2, 3,….,10 are called whole numbers. So, 1 is the smallest natural number and 0 is the smallest whole number. But there is no largest whole number or natural number because each number has its successor. Every whole number is made up of one or more of the symbols 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.

Is is a whole number?
Whole Number. A whole number is a member of the set {0,1, 2, 3, …}. It is either one of the positive integers (natural numbers) or zero. The set of whole numbers is exactly equivalent to the set of non negative integers.
4
Are all natural numbers are whole numbers?
Natural numbers are the set of positive integers, that is, integers from 1 to ∞ excluding fractional n decimal part. They are whole numbers excluding zero.Natural Numbers are also called counting numbers. Zero is the only whole number which is not a natural number.
5
What is the meaning of a whole number?
Whole numbers are positive numbers, including zero, without any decimal or fractional parts. They are numbers that represent whole things without pieces. The set of whole numbers is represented mathematically by the set: {0, 1, 2, 3, 4, 5}.
6
What is the meaning of odd number?
An odd number is an integer which is not a multiple of two. If it is divided by two the result is a fraction. One is the first odd positive number. The next four bigger odd numbers are three, five, seven, and nine. Some sequential even numbers are: {0,2,4,6,8,10,12,14,16}
7
What is natural numbers and their opposites?
1, 2, 3, etc.). Fractions and negative numbers are not natural numbers, but are the opposite of natural numbers. These negative numbers can be called integers. Zero is considered an integer (it is not a fraction or irrational number).
8
What is the definition of a composite number?
Composite Number. more A whole number that can be divided exactly by numbers other than 1 or itself. Example: 9 can be divided exactly by 3 (as well as 1 and 9), so 9 is a composite number. But 7 cannot be divided exactly (except by 1 and 7), so is NOT a composite number (it is a prime number).
9
Why is 0 a whole number and not a natural number?
Zero is known as the neutral integer, or the whole number that comes in the middle of the positive and negative numbers on a number line. Zero does not have a positive or negative value. Zero is however considered a whole number, which in turn makes it an integer, but not necessarily a natural number.
10
What is the definition of an even number?
An even number is an integer which is "evenly divisible" by two. This means that if the integer is divided by 2, it yields no remainder. Zero is an even number because zero divided by two equals zero, which despite not being a natural number, is an integer. Even numbers are either positive or negative.
11
Is the number 0 a real number?
A real number may be either rational or irrational; either algebraic or transcendental; and either positive, negative, or zero. Real numbers are used to measure continuous quantities.
12
Is a zero a number?
0 (zero) is both a number and the numerical digit used to represent that number in numerals. The number 0 fulfills a central role in mathematics as the additive identity of the integers, real numbers, and many other algebraic structures. As a digit, 0 is used as a placeholder in place value systems.
13
Do set of positive real numbers include zero?
In mathematics, the set of positive real numbers, , is the subset of those real numbers that are greater than zero. In a complex plane, is identified with the positive real axis and is usually drawn as a horizontal ray. The real positive axis corresponds to complex numbers.
14
Do whole numbers include zero?
The whole numbers are the numbers 0, 1, 2, 3, 4, and so on (the natural numbers and zero). Negative numbers are not considered "whole numbers." All natural numbers are whole numbers, but not all whole numbers are natural numbers since zero is a whole number but not a natural number.
15
Is the number 0 a rational number?
Moreover, we know 0 can be written as 0/1, we observe that both 0 & 1 are integers and the denominator i.e. '1' ≠ 0. So we conclude that '0' is a rational number and not irrational. We conclude that all whole numbers, all Positive and Negative Numbers are rational numbers.
16
Why is zero an even number?
Zero is an even number. As a result, zero shares all the properties that characterize even numbers: 0 is divisible by 2, 0 is neighbored on both sides by odd numbers, 0 is the sum of an integer (0) with itself, and a set of 0 objects can be split into two equal sets.
17
Is a repeating number irrational?
Recurring decimals such as 0.26262626…, all integers and all finite decimals, such as 0.241, are also rational numbers. Alternatively, an irrational number is any number that is not rational. It is a number that cannot be written as a ratio of two integers (or cannot be expressed as a fraction).
18
What is the first natural number?
Depending on the mathematician, the natural numbers include: 1, 2, 3, 4, 5, . . . (also called the positive integers), or 0, 1, 2, 3, 4, 5, . . . (also called the nonnegative integers or whole numbers).
19
Why is zero not a prime number?
Zero is not prime, since it has more than 2 divisors. Zero is even, since 0=2⋅0, and 0 is an integer. If we use "number" in essentially any of the usual senses (integer, real number, complex number), yes, zero is a number. Zero is not a prime number as prime numbers are defined for integers greater than 1.
